I'm trying to set up the practice data set for the Base Certification Prep Guide but for some reason I'm not able to add a file folder in the SAS Studio navigation pane to direct to the 'cert' folder on my desktop. Any idea why the 'new folder' option would not be available to me? I feel like I must be missing something very obvious here but it seems like I'm stuck unless I can create that folder, right? I'm running Studio on the latest version of Chrome on MacOS Big Sur 11.0.1.
